With. My new setup is a b16 block sleeved and bored to 84 mm. So im wondering in crome which basemap do i need to start with. b16 or gsr? And also, will crome support 1000cc injectors before i make my decison on the 650's. Im running 510's now.

I've always determined the type of basemap from the head and cams, adjusting fuel for more displacement is easy. Ignition timing isn't.

running 1000cc's is not easy to get to idle well, but it can be done.

 

Ok, cool. I already have the 650's coming tomorrow so ill be on those. And then my head is a stock b16, with ctr cams. So then i should be starting with the stock usdm b16 map then correct? Do i need to change the cc's for engine size?

Yes, you will want to start with a p30 base code, resize your injector multiplier, sync your ignition timing & start tuning from there.

 

What do mean by sync my ign. timing? Ive tuned al lil bit not really on a B series. I know how too add the boost options and pretty much everything else. But you lost me on that one. Thanks for the help also.

 

make sure your base ignition timing (with the distributor, a timing light and the service jumper shorted) is the same as the idle area of the map.

If you have datalogging, you just set the ignition timing at idle to match what Crome says it is running.

 

OOO!!! Got it. Thanks guys. So pretty much everything will be set at tdc and the dizzy timing at stock for the motor and make sure its the same for crome. Correct.
